摘要：

A dilatometer which has an absolute sensitivity of 10-4 Å with 5 s time constant is described. A coaxial resonator with capacity loading for 9·5 GHz serves as the sensitive element of the dilatometer. The changes in sample length shift the resonant frequency of a microwave self oscillator. The deviation of the oscillator frequency is detected by a heterodyne method using frequency modulation. The measurements can be carried out at specimen temperatures over the range from helium to room temperatures. © 1969.
